give me some explain to solve it. thanks

Consider three uniform charge distributions: . Spherical charge: Charge Q, Radius R, centered at the origin . Line of charge: Charge Q, Length L, on the x-axis, centered at the origin . Disk of charge: Charge Q, Radius R, on the x-y plane centered at the origin Sphere at x = y = z= 0 Line on x-axis Disk at z = 0, Radius R Length L Radius R Charge Q > 0 Charge Q > 0 Charge Q > 0 Z Z X Draw arrows at each circle showing the direction of the electric field due to the charge distribution. The dashed line is at a 45 angle from the x-axis. Consider the directions of the fields but do not worry about the relative magnitudes
